Well there is a way to get this figure from the Bible, but you need to do some work.
Basically, you start with Adam and, by using the genealogical information you arrive at a time span of 4004 years from Adam to Jesus, then add on the 2007 years since Jesus was born (yes I know they got the wrong date), then you essentially have a creation of the universe around 6000 years ago.
The guy you want to look up is Bishop Ussher, he arrived at the creation date of 4004 BC.
There's some info here

This only applies to a 24 hour day requiring a sun & moon so all the Ussher date applies to is the age of animals and man. Everything else was created before the 24 hour day, so no the Bible does not support a 6000 year planet earth. Nor does it support a 6000 year sun & moon. Nor does it support 6000 year plants.
The Bible does not designate the length of the days before day 5 after the sun and moon were created.
